[Therion] How to include hand calculated cave length in legend?

2 Mar 2018

      Hi,

I want to include in the legend box a cave length I calculated using a
method different from Therion's automatic one.

How can I do it?

Let's say I would like to include "Desenvolvimento linear: 178 m" just
above the Depth info in the legend?

Regards,

Rodrigo Severo
